Windows suddenly won't recognize my HDD prior to installation.

[Chaosblade02]

This is a brand new HDD that was working. I was trying to get intel smart response working, but it merged by SSD and HDD together in raid 0 by default when I changed the file type to RAID, so I had to undo that in the raid options. And after I did, windows will no longer see my HDD in any file setting. But the BIOS and raid controller menu both see the HDD. I don't get it, if its bad the bios shouldn't see it either.

How do I get windows to see my HDD?

Just how did it merge them together?
If it was destructive, then, if you didn't have backups, your in for a rough ride trying to get the data back.
If it wasn't, then if you are lucky, you can use the windows recovery console to rewrite the MBR and possibly the boot loader--it may or may not work, it really depends on how it did the merge.

Boot to a Live CD and take a look at the disk. You might get some clues from that.

When you set the file type to RAID in the bios, it merges the drives in raid 0 by default it seems, and you have to go in the raid controller and separate them if you are trying to do intel smart response. Because Intel rapid storage technology wont let you set the SSD as a cashing device if it is already merged with the HDD in raid 0.

I am not really concerned as much with the data, because this is a pre-windows install, I had nothing on there to begin with.

I am pretty sure the HDD is still good, but not 100%.

I just want windows to see the HDD so I can put windows on it. Is it possible separating them cleaned everything off the drive including partitions, and drivers installed on the HDD? How would I go about putting those back on the HDD?

diskpart
list disk
select disk 1 ; make sure its the correct number
clean
create partition primary
active
format quick
assign

Check Explorer for your new drive.

You could also use a tool like Acronis partition recovery. Should fix it in the blink of an eye.

You did check device manager or disk management right?
